The 2.0 Mappers are currently available in Rossini DAC, Rossini Player, Vivaldi One and Vivaldi DAC as well as the APEX models of these products. On May 31st 2022 we will release a software update for Bartók DAC and Bartók Headphone DAC to enable the 2.0 Mappers in these products too.
Lina DAC is a different hardware architecture than two channel dCS products. This is in part because of the chassis size and the single flex board design. The Lina DAC will run the standard (classic) Mapper, which is the same as Mapper 2 on Bartók, Rossini and Vivaldi ranges. Currently the APEX Ring DAC is available in Vivaldi and Rossini only.
